5.Go to DUMP folder and create List type in view folder.
Choose ascend and you can find this file "FE354FE..ROM" (it has size more than 500 KB)
6.Copy this file to folder differ from DUMP.
7.Download any hex editor, i use HxD,it is free.
8.Open FE354FE..ROM with hex editor and search for these magic bytes which Dudu2002 aka Oleh use.
-"7C A6" for Lenovo Y50-70,S400,Yoga 2-13,G400s,G580,G780,G480 and etc.

13.Now you can press OK and wait until tool will complete new modded bios.
14.Enjoy!
Modder Oleh aka Dudu2002 knows only these magic bytes no more.He cannot unlock hidden settings for Acer, Sony,HP, Toshiba, Dell and other Lenovo because he's modding level is too low.
If these magis bytes can not be found, it means you have old or new Lenovo laptop.
Owners of new Lenovo laptops must have SPI PGM+Pomona SOIC8 clip to flash mod.

BDMaster :

I made a big wrong to be good and theach himn a lot of mine knowledge to make Insyde and Phoenix modifies , when He copied from CodeRush (habr.com) ...

There are a bunch of bytes like these, but the main thing is that they should be in the neighborhood.

So it means you did not find magic bytes (if the specified chains are in your BIOS at all).

Also, it seems that you have already get the mod for your Z500. Send the FE3542... file in PM if you want me to take a look at it.

Hi there,

Thank you for writing up this guide.

I would like to unlock the bios of a Lenovo Y50-70, would i have to install Windows 7 on the machine to run the x64ra8 file ? Or any other recommended workarounds ? Thanks

I have the same doubt. there're many magic bytes but those aren't next to them. They are in different rows.
How can I know what of all the bytes I need to edit?
